RECEPTACLE CLOSURE.

Application filed my 19,1926. Serial No. 110,173.

This invention relates to improvements in receptacle closures or caps, with the ob ect 1n view of providing a re-closure which may be readily applied to and removed from the re- 5 ceptacle, and will, when so applied, be held firmly in place against accidental displacement.

Another object consists in (providing such a re-closure as may be used in efinitely without any appreciable decrease in the firmness" with which it grips the receptacle to WhlCll it is a plied.

A iixrther object consists in" provid ng such a re-closure having a double, successive grippin action.

' A 'sti 1 further object consists in providing certain improvements in the -form, construction and arrangement of the parts whereby the above mentioned and other objects may be attained more effectively than heretofore. A practical embodiment of my invention is represented in the accompanying drawings, in which Fig. 1 represents a side view artly in vertical section showing the re-c osure in position u on the receptacle before removal of the sea which is here represented as an ordinary crown seal,

Fig. 2 represents a vertical sectlon showing the receptacle and re-closure in effective englagement therewith, after removal of the sea The receptacle, of which only the upper portion is shown, is denoted by 1, and represents, by way of example, an ordinary catsup bottle. It is provi ed with an annular projecting head 2, located a short dlstance from the mouth of the receptacle, and with an annular enlargement 3 intermediate the bead and the mouth. The head 2 and enlargement 3 may be of ordinary size and shape, such as are commonly fashioned upon bottles of this nature.

The re-closure 4 may, if desired, be of integral construction or formed in any other approved manner. It is here represented, by way of illustration, as of the twoiece type,

comprising a body portion 5 an a top 6,

seamed together in a well known manner at 7. The lower edge may advantageously be rolled or folded as indicated at 8, w ich serves the double purpose of concealin the cut edge of the material forming the b y of the cap and of reinforcing that edge against accidental distortion.

vitreous material, such as glass.

Additionally, the closure 4 may be composed of some relatively elastic or sprin material, such, for instance, as lacquered tin, while the receptacle 1 will generally and naturally be composed of some unyielding, C9

The cap body 5 is of a size to slide easily over the enlargement 3 and is provided, at some distance from its top, with an annular series of elongated indentations arranged in pairs as shown at 9, 9. .These indentations are preferably so-distanced from the top and bottom of the cap that they willlie just below the enlargement 3 when the cap is applied to the receptacle with its lower edge 8 impinging firmly upon the annular bead 2, thus limiting the downward movement of the can.

The indentations 9, 9 thus form, on the 1 inside of the cap, a series of ridge-like projections which'spring aside in passing over the enlargement 3 to allow the cap tobe applied, and yet offer suflicient resistance by their engagement with the lower art of the enlargement 3 to prevent accidiental displacement of the cap.

10 is a seal of any usual form, here shown as a crown seal.

When it is desired to 0 en a new bottle sealed as shown in Fig. 1, t e re-closure 4 is removed by hand, the seal 10 is removed by' a suitable instrument and the contents of the receptacle is available for use; After pouring out the desired quantity, the receptacle is re-closed by applying the closure 4-, as shown in Fig. 2. In this position dustproof contact is formed between the lower edge 8 and the annular rejecting head 2 of the receptacle. The in ented portions 9, 9 engage the enlargement 3 below its point of greatest circum erence and so operate to hold the closure firmly down u on the bead 2 and insure the tightness of e joint just. mentioned.

The arran ement of the indentations 9, 9 in pairs as iown has been. found of great advantage in several respects.- Each member of a pair serves to strengthen the other and the firm gri ping action resulting there-; 1 from does not iminislr to any ap' reciable degree during the whole useful h e of the filled rece tacle; in this respect there results a su antial improvement 'over caps having a series of single depressions which have been found to soon decrease in useful- 110 The lower series of indentations will engage the receptacle to an appreciable degree even when the cap is carelessly ap lied. It is evident that in a cap having but a single series of gripping parts (which must correspond to the upper series in the cap here shown), there can be no effective gr pping of the receptacle until the cap has been completely seated. v

The narrow, ridge-like form of the indentations enables them to resist quite stifliy any deforming forces, with the result that a much more ositive engagement is secured than that obtained by a fiat plateau-like area such as has sometimesbeen suggested for this purpose.

It will be understood that various changes may be resorted to in the form, construction and arrangement of the several parts without departing from the spirit and scope of my invention; and hence, I do not intend to be limited to the details herein shown and described except as they may be included in the claims.

What I claim is:

1. A sheet metal receptacle closure including a cylindrical body portion provided with a plurality of sets of horizontally disposed elongated indentations spaced from the top of said body ortion, the indentations of each set forming on the inside of the body portion ridge-like projections adapted to engage the wall of a receptacle to hold the closure removabl in place thereon, the distance between a jacent indentations of each set being not greater than substantially one twentieth of the circumference of said cylindrical body portion.

2. A sheet metal receptacle closure including a cylindrical body portion provided with an annular series of sets of horizontally disposed elongated indentations spaced from the top of said body portion, the indentations of each set forming on the inside of the body portion ridge-like projections adapted to engage the wall of the receptacle to hold the closure removably in place thereon, the distance between adjacent indentations of each set being substantially less than the length of said lndentations.

In testimony, that I claim the as my invention, 14th day of May, 1926.
